A track plan works as a whole not as isolated small screen grabs, and that is especially true for reversing loops. I provided advice based upon what you provided. When you ask for advice then the best way to get it is to provide all the information, if you don’t want to do that then considered advice isn’t possible.

It also sounds like you have already decided your track plan therefore asking for advice without changing based upon the advice makes this a nugatory exercise.
Iain, Heh, I wasn't really asking for advice on the track plan, just checking on how to wire up the reversing loops especially in the Digikeijs/YaMoRC world. This track plan is verson 60, so it's been going on for a while now. The whole layout is loop-to-loop over 2 decks. There is yet another staging yard underneath for the other end of the mainline. iTrain or TrainController needs to know about all of the tracks with Railcom detection.
Your answer is not the greatest news, but one I really needed to be confirmed. If it's impractical to put lots of detected blocks inside a reversing loop, then it looks like I will be buying a lot of DR5013's (or the YaMoRC equivalent if/when it becomes available.). This brings it up to around 12 units.?
I've not seen anyone else recommend the short-circuit switch mode, so your comments were useful. Thanks.
